IMPROVEMENT IN CLlPPlNG-MACHINES.

Specification forming part of Letters Patent No. 179, 105, dated June 27, 1876 application filed April 10, 1876.

To all whom it may concern Be it known that I, ALBERT N. GAVIT, of Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Machines for Clipping Horses, Sheep, Dogs, 8w;

and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part hereof.

My invention consists of the combination, in a clipping-machine, of two levers, pivoted together, as hereinafter shownone having at its extremity a comb-plate, and the other a curved rack gearing into a curved gear, which operates a serrated,toothed cutting-plate; also, of the combination, in a clipping-machine, of two levers, pivoted together, as hereinafter shownone of said levers having at its extremity a comb-plate, all in combination with a serrated, toothed, rotary, vibratory cutter, operated by said levers and intermediate gear To enable others skilled in the art to make and use my invention, I will describe its construction and operation.

In the drawings, Figurel is a plan view of my invention; Fig.2,an enlarged cross-section on the line X Y of Fig. 1.

A is the ,combdisk; B, a shaft or standard, rigidly secured by a screw-thread, or rivet or bolt-head, to comb-plate A; O, a'revolving cutting-disk on the shaft B, having serrated cutting-teeth D; E, a cogwheel, rigidly at tached to disk 0; G, a washer; H, a screwnut on top of shaft B, to keep washer Gr, cogwheel E, and disk (3 in place, and to sustain the latter close againstcomb-plate A. I and K are handles, the latter being pivoted at L. M is a curved rack on the extremity of handle K, furnished with cogs to gear into cogwheel E.

The contiguous sides of disks A and (l are concave, as shown in enlarged Fig. 2, nearly to the inner ends of the comb and cuttingteeth. In that figure in the drawing I have slightly exaggerated the degree of concavity to show it more plainly. The edges of teeth D are beveled sharp, the outer edge of the bevel being next to the comb-plate A. The handle I is attached to the comb-plate A by screws,

and is thus detachable from it. Though the comb-teeth radiate from a common center, it will be seen that the edges of contiguous teeth are close and nearly parallel.

The operation is as follows: The handle I is taken in one hand, and handle K in the other, and the comb-teeth on disk A are pushed under and through the horses hair; at the same time handle K is moved from and toward handle I like shear-handles. The out-stroke is stopped by a thick check-tooth on the right end (in the drawings) of rack M, which will not enter the gears of cog E. The back-stroke is checked by handles I and K meeting each other. This motion, through the medium of gears M and E, operates to revolve with a vibratory motion the cutting-teeth D, which cut off the hairs projecting up through the comb-teeth. These teeth D pass directly over and touch the comb-teeth, and each hair to be out is caught between the edge of the cutting-tooth and the edge of the comb-tooth, above which it projects, and toward which the cutting-tooth is proceeding. This operates to nip the hair off in the same manner as harvester-teeth, between themselves and the fingers of the beam, nip off the grain-stalks. The knives or cutters G are sharpened by detaching the disk (3 and rubbing its concave side down upon a grindstone or flat stone,and it can be sharpened to any extent-in fact, until it is worn through. Of course, it is to be rubbed upon the same side as the concavity is placed. The same course can be pursued with disk A by unscrewing or detaching the shaft B from it and removing the handle I. The nut H will follow disk (3 down on the shaft or standard B, as the disks are Worn thin by repeated grindings. The degree of revolution of disk (3 can be regulated by varying the relative sizes of rack M and cog E.

The smaller the latter is in proportion to the former the greater is its revolution and speed. By changing disk 0 around occasionally the wear will be equalized. I

From the length of the cutting-edge of my clipper or shearer, sheep, horses, and dogs can be rapidly clipped, while the roundness of the edge makes it an easy matter for the operator to reach all parts and depressions of 2. The combination, in a clipping-machine, of two levers, pivoted together, L, one of said levers having at its extremity a comb-plate, all in combination with a serrated, toothed, rotary, vibratory cutter, operated by said levers and intermediate gearing, substantially as described.

ALBERT N. GAVIT.
